58 and a Half Hours/Setting Notes
Non-Spoiler Information
While parts of the story's genre morphs throughout the story, the harem genre sticks the whole way through. High School drama is it's other starting genre, starting out.
The Underwood's home is supposed to be in one of the outer suburbs of Denver, Colorado. You may be wondering, why all the Japanese names then? The in story reason, for Yuu's family anyway, is because Yuu's maternal grandmother was adopted by Japanese/American couple, which led to mostly Japanese names being used for the following two generations. The out of story reason is because, though I chose the last name before beginning, as I made up Yuu's family I asked my wife to pick names for them (yes, even creepy perverts can sometimes manage to get married). Since she's kind of an otaku, she ended up choosing mostly Japanese names for the maternal side of Yuu's family. The Japanese names for the students at the school, though? The blame falls entirely on Artificial Academy 2's name generator. That being said, it really isn't critical that the names match the ethnicity of the area or people using them.
There's about half a page of other stuff I could add, but it's all spoilery to some degree or another, so at the moment I think I'll only add it if I can find a good way to hide it so that you're not automatically spoiled by visiting this page.
